We use only the relative url that is passed by IContent
and its UrlWithExtension.
The property return something like "~/filename.sflb.ashx". Then we use Telerik.Web.UrlPath.ResolveAbsoluteUrl( string param) to resolve the url, but this is done on the client for the current host
. So, you are running your website on port 6238 and this is why you see it in the url.
